Rule based marketing (or programmatic marketing) is getting more & more targeted. It started back with Google PPC and you could set the rules that if a person is in your city & search “homes for sale in (city)” that your ads would appear. Marketing has evolved since that. Now rules are being created based on our behaviours, what we are looking at, what device we are using, our social media profiles… and so much more! As a real estate agent you can use rule based marketing to only connect with the RIGHT people, at the RIGHT time :-) This video shows some examples.
